%
% Colorlessly plots individual fuzzy numbers of a linquistic vector.
% All alphas are assumed to be uniformly distributed between [0,1]
% The lingustic vector of m dimensionality and N alpha granularity 
% is assumed to be stored in a matrix of size [N,2*m] 
% with format [[l1,h1],[l2,h2],...,[lm,hm]].  
% Generates a new figure everytime, so watch your counts if you use this often.
% Truly this is just a stub function, and far more robust methods of visual
% representation can and should be developed.
